onnmr n eoiuniivv, Uu'iED;) or LONDQX, ENGLAND? i Toaib' 071 0711, itmay concern.- .lleit known that l, ALFRED (fl KOERNER, a subject of theQueen of England, residing in\laris,"France; have invented certain newand useful lmproteinents in 'lraining' Mechanism-for Ordnance, fullydescribed and rep:

resented in the following specification and the accompanying drawings,forming a partlot the same, the said improvements being en1 braced inl"'-r'en('h Lctterslatent, N0. 183,-?3- dated January 113, 113811 Y Thisinvention relates to improvements in traini ng or poi n ti neiap,p;;itusiorrapid-ii ring or other guns; 1

It is the object of ihepresent invention to provide mechanism for thispurpose by which theoperationsof pointing; both horizontally andvertically will be rendered easier and can be accomplished"with greaterfacility and rapidity than in: mechanisms heretofore cone i'nonly-usedfor this purpose.

'ltis also the tion to so construct and arrange the mechanism for roughpointing horizontally that when it is desired to move the gun to anygreat extent horizontally in rough pointing this mechanism may be thrownoutot' operative connection with the gun-carriage so as not tointerfere'with the horizontal movement oi the gun.

, The mechanism for finepo'int-ing horizontally consists, briefly, of .aworm-wheel upon the lower-part of the ginrcarriagc, with which engages aworm mounted on a shaft journaled in a frame pii'otedto the upper partof said carriage, said shaft and worm being operated through suitableconnections byimeans of a shaft amthand-wheel extending to the rear, ofthe gun to cause the uppcrpartot the car riage, and with 'it the gumtorevolve in a-l-ho'rizontal path uponthe lower part of the ear riage."The frame in which the worm-carrying shaft is mounted/ is connected to adirect ingle\ "e r, so that when the latter is raised the worm will bethrown out of engagement with the worm-wheel upon the lower part of thegun-carriage, and thus permit the movement of the gun horizontally to beaccomplished quickly and easily in rough pointing.

The mechanism for pointing vertically consists of an elevating-screwconnected to the object. of the present inven carriage.

pivoted in, arms upon the upper part'of the guncarriage;said screw beingraised and lowered-to correspondingly move the gun through suitableconnections by means of a hand-wheel located -atthe rear of the gun.

provements constituting the-presentinvention are equallyapplicable toguns of other types. The gun A ismounted in the usual-manner ,upon itscarriage, which is made in two partsvia, a base dand an upper part 1).The gun is trunnioned upon the upper part]; of the The upper part Z) ofthe carriage is mounted upon the base a', so as to be free to berevolved thereon. The base d of the carriage is circul-a-rin form at itsupper edge, and is provided with a worm-wheel c, with which normallyengages a worm d. The worm d is carried by a shaft 0, jonrnaled inbearin formed upon the lower end of a U-shaped frame j}.

suspended pivotally from the upper part b of the carriage by means ofpivots h entering bearings 'i, providcdin the upper ends of the frameupon opposite'sides of the gun A. The

' shaft (2 has secured to it at one end a bevel gear-wheel 7, with whichengages a second gear-wheel Z',carried by a shaft? 1:, extending towardthe rear of the *gun and provided at its'end witli a hand-wheel j,located in convenient position to be grasped by the'gunner.

The shaft k is journaled in a downward extension y of the shoulder-piecea-, forming one with thedirecting-lever g, which in turn is made'integral with or connected to, the

frame f.

\Vith the mechanism thus constructed and arranged the operations ofrough pointing and fine pointing horizontally are accomplished in thefollowing manner: To move the 10o under. side of the gun andworkingin'anut backward, and thus take the worm d out of engagement withtheworm-wheel 0., \Vith the worm d in this position the gunner by means ofthe lever 9 will revolve the gun and the upper part b of the carriageupon the base a into the desired position horizontally. By then;lowering the lever g the worm d and worm-wheel 0 will be again broughtinto on gagement.- To adjust the gun accurately horizontally to bring itin line with the ob ject at which-it is desi td to fire, the gunnerwill, by turning the hand-wheel J and shaft 70, operate the bevelgear-wheels ZZ and through them cause the revolution of the shaft 6 andits worm d. As the worm d is thus revolved, it will travel around theworm-wheel 0' upon the base a of the carriage, and being connected tothe upper part of said carriage will cause it, and with it the gun, torevolve upon the base a. This movement will be continued until the gunis properly pointed horizontally. The gun will then be adjustedvertically to proper position for firing by means of the mechanism whichwill now be described. This mechanism consists of an elevating screw m,pivoted to the under side of the gun A, near its rear end, by means of apivot n, its lower end working in a screw-threaded nut 0, mounted andturning in a collar 0' pivoted between arms 1:), projecting rearwardlyfrom the upper part b of the carriage. The nut 0 is provided atits'lower end witha wormwheel I, with which engages a worm 15', carriedby a short shaft 8, connected to a rod '1', which in turn is connectedto a shaft .2, mounted in an'extension of the directing-lever g andprovided with a hand-wheel q. The shaft 5 and the shaft 8 are connectedto the rod 1' by universal joints to M, respectively, by means of whichconnection they are adapted to angular motion caused by the elevationand lowering of the gun from its horizontal position and by the raisingand lowering of thedlreetinglever g. To elevate or depress after the gunhas been properly adjusted horizontally, the gunner, by turning thehand-wheel q and shaft 2, will, through the rod 7", shaft 3, worm t, andworm-wheel t, turn the nut 0 about the elevating-screw m and cause saidscrew to move upward in said nut, thus depressing the gun for firing. Toelevate, the gunner will turn'the hand-wheel in the opposite direction.When the gun has been-pointed as described, the gunner, by drawing uponthe lanyard 1.0,will cause its discharge. The lanyard w will preferablybe locate'd,as shown in the drawings, with its end connected to a handleas, mountedin the extension y of the shoulder-piece r, beneath thehand-wheel j, in substantially the mannershown in my Letters Patent No.394,190, thus bringing the firing mechanism into convenient position tobe operated by the gunner without changing his position after theoperations of aiming. By thus constructing and locating the mechanismsfor rough pointing and fine pointing horizontally, pointing vertically,and for firing, the several mechanisms are within easy reach of thegunner without changing his position at the rear of the gun, thusinsuring facility and rapidity in the various movements and the firingof the gun.

. It will be'obvious that the connections for operating the mechanismsfor fine pointinghorizontally and vertically may be somewhat modifiedwithout departing from the spirit of my invention.

What I claim isof the worm-wheel 0 upon the lower part a of saidcarriage, the worm (Z, engaging therewith and secured to a shaft e,mounted in a frame suspended pivotally from-the upper art I) of saidcarriage, the hand-wheel j, shaft 0, and connections for rotating saidshaft 6, substantially as described.

2; In a rapid-firing or other gun, the combination, with its carriage intwo parts a b, of the worm-wheel 0. upon the lower part a of saidcarriage, the worm (l, engaging therewith and secured to a shaft '6,mounted in a frame f, suspended pivotally from the upper part of saidcarriage, bevel gear-wheels for rotating saidshaft, the hand-wheel j,and

shaft k, for operating said gear-wheels, and

the directing-lever g, connected to the frame f to swing the same,substantially as described.

In a rapid-firing or other gun, the combination of the elevating-screwm, pivoted to thegnn and working in a nut o, suspended from thegun-carriage, the worm-wheelt upon said nut, the worm t, engagingtherewith, the shafts s and 2, connected to the rod 1' and carrying theworm and hand-wheel, respectively, and the hand-wheel q, for operatingsaid shafts and rod, substantially as described.

In testimony whereof I have hereunto set my hand-in the presence of twosubscribing witnesses.
